The research objective was to diagnose aluminum gearbox castings using the proposed diagnosis methodology and pro-quality analysis. The study identified the most severe non-conformity (in terms of frequency of occurrence and its consequences) – the sandblasting within the casting base. The presence of forming compounds in the liquid melt contributing to the most severe non-conformity was identified as the critical cause of the loss of quality stability of the process. So far, no pro-quality analyses have been performed in the company using a sequence of quality management methods. As a result, the implemented corrective actions have not led to the full achievement of quality objectives, which indicates the validity of the actions taken. Combining the analysis of types of nonconformities and quality management methods is a universal way to facilitate supervision and ensure appropriate product quality. Further studies will refer to the performance of pro-quality analyses for other products offered by the company.
